The bill would extend and renew a program that studies shared underground water sources between the United States and Mexico, helping both countries better understand and manage these critical water resources. This affects border communities, farmers, and water utilities that depend on these aquifers for drinking water and irrigation. The program allows scientists and officials from both nations to work together on research and monitoring of these transboundary water supplies.
